Weak Winter (so far)
December 29, 2011 5 Comments
So far, much of Michigan is in a snow shortage!
With a glancing blow from a low pressure system on Tuesday, we finally have some white stuff. The snow formation on the backside of the storm, aka deformation snows, were relatively light as moisture was lacking. Even still, a cover of 1-3 inches was widespread. Behind it, strong winds ushered in cool air that dropped wind chills into the teens.
Looking ahead, it will be a slop fest once again. Mixes of rain and snow can be expected over the rest of the week. At night when temperatures drop, light snow accumulations will be likely. A quick ‘clipper’ disturbance moves through Thursday/Friday before the Arctic chill strikes late this weekend. A powerful storm will pass to our north initially bringing rain. Once the associated cold front passes through, any lingering rain will change over, but the big story of this storm will be the cold air behind.
Monday we will be looking at daytime highs in the lower 20s. Enjoy the warmth while it lasts!
Recently in Birmingham, Alabama a very unique cloud was spotted! Kelvin-Helmholtz wave clouds are truly a stunning sight.
I constantly am learning and sharing how fluid the atmosphere is, and how it relates to the liquid you may be taking a sip of now! The Cloud Apreciation Society labels these iconic wave clouds as nothing short of a water wave in the air:
The breaking waveforms of ‘Kelv-Helmz’ (as they aren’t known) are the result of shearing winds up at cloud level. A particular type of turbulence can develop in a layer of Cirrus cloud, which happens to form below an inversion* between air currents of differing speeds and/or directions. Sea waves break as their bases are slowed down upon reaching shallow water and their crests surge ahead. Cloud waves break in the same way: when their crests are pushed ahead of their troughs by the difference in air currents.
Now you know! Plenty more pictures of this event (including the one used above) available here.
